The Kingdom of ancient Sulu lies in the Sulu Islands between Kalimantan Island and the Philippines. The kings of west and east Sulu visited China in 1417 during the Ming Dynasty (1368-1644), followed by 340 envoys, and received a warm welcome from the Ming government. The king of the east died in Dezhou on the way back and was buried there. His eldest son returned to Sulu soon after and took the throne. The deceased king's wife, his second son, third son and servants stayed behind in China to mourn over him. The queen returned to Sulu in 1423; her two sons and other servants remained, and were buried to the east of the king's tomb.

The tomb yard, which is filled with pine trees, is located one kilometer north of Dezhou City. The coffin chamber is situated at the center with the tomb tablet in front. Both sides of the passageway are lined with stone animals. Since the Ming and Qing (1644-1911) Dynasties, many tourists have visited the sight to pay their respects to the friendly king of the Philippines.
